Titles

I keep editing the titles for movies like: Jurassic World Dominion Jurassic World Rebirth And my edits get approved and they stay there for a solid week, then someone comes along and adds a colon back in. These two movies as per Universal Pictures and the official billing blocks do not use a colon. (I've had similar problems with Alien Resurrection and It Chapter Two, but those finally stopped.) How do I get IMDb to lock those titles with no colon? Jurassic World: Fallen Kingdom DOES have one.
